“… you don’t have to trick them…
It’s not like people don’t want to spend money, they want to spend money on things that they love and they want to be charged honestly.They don’t want to be like ‘I’ve run out of energy?’ They want to feel like it’s not monetisation based on they need to move forward, it’s monetisation based ‘I want to do this.’ When you move from need based monetisation to want based monetisation you think about things differently as a user, you don’t begrudge spending the money. I think in Japan they’re much further along that curve.”

People want to spend money on the things that they love. Things that meet their needs, that entertain them and on things that feel valuable to them.
